Abstract
The invention discloses an electric energy meter. The electric energy meter comprises an electric energy metering module and power modules. The power modules comprise the power module A and the power module B. Both the power module A and the power module B are pluggable. Compared with the prior art, the two power modules are adopted for supplying power to the electric energy meter; if either power module is damaged, the other power module will automatically bear 100 percent of electricity load, at this time, only the damaged power module needs to be pulled out and replaced with a new power module, and therefore the working stability of the electric energy meter is improved.
Description
Technical field
The invention belongs to electric power meter and manufacture field, particularly relate to a kind of electric energy meter.
Background technology
Traditional electric energy meter at the scene operation time be all a metering outfit electric energy meter, but in the Centralized Monitoring of IDC data center module, often a first cabinet of each row just has tens loops to need monitoring, at this moment carry out monitoring the problem chosen and connect up that will run into electric energy meter installation site according to traditional electric energy meter, in limited space, be difficult to the installation realizing single channel ammeter, construction wiring is also just more difficult.In addition, because guaranteeing that data center apparatus can normally work, therefore the design of power supply many employings dual power supply of data center, one tunnel is main, one tunnel is for subsequent use, two-way power supply needs power supply to the device simultaneously, one road power fail or power-off can not cause not working of data server, traditional ammeter is all single supply design, cannot be met this and use scene, exchange dual power supply input and must ensure the electric current of monitoring circuit ability consistent with the monitoring voltage phase place in this loop accurate-metering energy data when carrying out the metering of electric energy, therefore this monitoring equipment also must meet dual power supply design can the consumer of accurate-metering monitoring circuit, the monitoring equipment of data center requires higher than the measuring products stability under general environment and maintainability require, the product of a lot of company is all adopt integrated design, if there is a monitoring circuit to break down, complete machine then can be caused to change, in Renewal process, also can cause the loss of data, this brings constant greatly to later maintenance.
Therefore, be necessary that proposing a kind of new electric energy meter solves the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of holding part device solved the problems of the technologies described above.
Wherein, this electric energy meter, comprising: electric energy metering module, power module, and described power module comprises power module A and power module B, and described power module A and power module B is all pluggable.
As a further improvement on the present invention, described power module A and power module B can be energized work simultaneously, and can distribute electrical current by automatic average.
As a further improvement on the present invention, as described power module A or described power module B power-off, described power module B or described power module A can accept whole power loads automatically.
As a further improvement on the present invention, described power module A and power module B is all hot-pluggable.
As a further improvement on the present invention, described electric energy metering module refers to voltage acquisition card, and described voltage acquisition card is hot-pluggable.
Compared with prior art, the present invention adopts dual-power module to power to electric energy meter, if there is arbitrary power module to damage, another power module can accept the power load of 100% automatically, now only need extract damage power module, the power module more renewed, enhance the job stability of electric energy meter.
Accompanying drawing explanation
Fig. 1 is electric energy meter operating diagram in an embodiment of the present invention.
Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments, method or conversion functionally are all included in protection scope of the present invention.
In an embodiment of the present invention, described electric energy meter, be used for the voltage of monitoring equipment load, comprise: electric energy metering module, power module, wherein, power module comprises power module A and power module B, power module A and power module B is separate, power module A is that primary power is powered, power module B is that standby power supply is powered, 2 supply modules can be energized work simultaneously, autonomous equalizing current provides power supply to apparatus of load, each power module bears the power load of 50% separately, if when power module A or described power module B power-off, power module B or described power module A can accept the power load of 100% automatically, guarantee the normal operation of electric energy meter.
Particularly, shown in ginseng Fig. 1, power module A is electrically connected voltage acquisition card 1,2,3,4, power module A provides power supply to the voltage sample of voltage acquisition card 1,2,3,4, power module B is electrically connected voltage acquisition card 5,6,7,8, power module B provides power supply to the voltage acquisition of voltage acquisition card 5,6,7,8, and now in data center's first cabinet of each row, the alternating current equipment of dual power supply just can realize the accurate-metering of electric energy.If when power module A damage or power-off, power module B just powers to voltage acquisition card 1,2,3,4,5,6,7,8 simultaneously, otherwise, if when power module B damage or power-off, power module A just powers to voltage acquisition card 1,2,3,4,5,6,7,8 simultaneously, but this pattern only having power module A or power module B to power separately is a temporal transition just, still need the power module changing damage or power-off as soon as possible.It is worth mentioning that, power module A and power module B all adopts pluggable design, and tenaculum hot-line insertion and extraction, if there is arbitrary power module to damage, only need extract the power module of damage, the power module more renewed is just passable, voltage acquisition card 1, 2, 3, 4, 5, 6, 7, 8 also adopt pluggable design, and tenaculum hot-line insertion and extraction, if there is arbitrary voltage acquisition card to damage, only need extract the voltage acquisition card of damage, the voltage acquisition card more renewed, post facility is safeguarded and offers convenience, too increase the reliability of equipment simultaneously, the design of double loop power supply achieves the accurate-metering of racks of data centers equipment in different electrical power situation, the electricity consumption situation of equipment of can distinguishing in real time in different electrical power situation and relevant electric parameter.
Be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
